Optical excitations in PPV aggregates

Thin Solid Films, 2000
Abstract Linear optical responses of large PPV (poly(p-phenylenevinylene) aggregates have been investigated numerically using the linear-scaling (LDM) method. The semiempirical CNDO/S (Complete Neglect of Differential Overlap in Spectroscopy) Hamiltonian is adopted in the calculation.

Optical excitations in C60/PPV composites

Journal of Non-Crystalline Solids, 2006
Charge transfer (CT) and subsequent exciton dissociation are essential for organic donor/acceptor solar cells. We analyze these processes by calculating optical intrachain and CT excitations in a model donor/acceptor system. It is found that the increased electron affinity of low-gap polymers may seriously inhibit the CT efficiency.

Optical Properties of MEH-PPV

AIP Conference Proceedings, 2011
Three and five layers of synthesized and commercially available of MEH‐PPV thin films were prepared by spin coating technique. Toluene was used to prepare the MEH‐PPV solutions and the solutions were deposited onto glass substrate. The optical properties and surface morphology of MEH‐PPV thin films were studied.

Maximizing PPV in C3I systems

SPIE Proceedings, 2017
In this paper, we present a new concept of enhancing Positive Predictive Value (PPV) useful for 3rd offset C3I systems, based on target-oriented binary sensor sets.
